I installed thunderbird on my new Samsung A26. I tried to configure the imap connection for my email - provider is liwest.at - per their settings. the incoming mail check worked. but the outgoing mail check gives back the error "unable to parse tls packet header" I checked username and password multiple times and tried all versions of password authentication possibilities.

I googled the error but the only thing I could find was a possible mismatch in tls versions. I asked my provider about it - their customer service could not confirm with their technicians what version is in use but according to their documentation it should be tls 1.2

Importing encryption keys from TB Desktop to TB for Android

Hello,

I have read this one https://support.mozilla.org/en-US/kb/openpgp-thunderbird-android-howto and I was aiming for additional detailed info on a specific step in the "Select an encryption key or create a new key" section.

From Thunderbird Desktop I can already send/receive encrypted emails from a specific email account and I have exported, on my laptop, my private and public keys as well as the public keys of some contacts.

On my Android phone I have Thunderbird for Android (version 14) already set up for the same email account and, in order to start using email encryption, I understood from the above link that I first need to install OpenKeychain and then, from the image in step 2 of "Select an encryption key or create a new key" and from the text of the subsequent step 3, that I'll need to choose "I already have a key. Import end-to-end key from other device" and then, if I got it right, try to find the keys which I exported on my laptop from Thunderbird Desktop.

Are there any precise details on how to find those exported keys and load them into OpenKeychain? Meaning, for instance, do I need to copy/paste the keys from my laptop into the archive of my Android phone and then direct Thunderbird/OpenKeychain to that location to pick them up?

Any type of details/links/docs/videos with respect to this, will be useful. As well as any explanations in case I understood wrongly and what I am trying to do is not the proper way to proceed.

Please note: I am not an expert.

Thank you

Best Regards

Certificate validation on Imaps

Hi, I'm trying to find out where (in the code) the app checks the server certificate. I consider myself a programmer (thanks Edsger!) but after some browsing I did not find the way in the repo.

The issue is that in my experience, every time the server cert is changed (Imaps, LetsEncrypt) k9 asks me to validate the new cert. And I have 2 things I want to check: -Another user says he is also using K9 and he's never presented with a cert issue on change -I want to see the possibility of directly accepting the new cert iif stored cert is about to expire, new cert comes from the same authority (root CA) and PK is the same.

Any help in this regard is appreciated! -Carlos
